Supported IC Models & Chips
The EU5 is unique because it supports several high-end and mid-range Exynos chips, including those found in the Samsung Galaxy S21 series and newer budget-friendly models.
Primary CPU & RAM Support:
-
Exynos 2100: Found in the flagship Samsung Galaxy S21, S21+, and S21 Ultra.
-
Exynos 1080: A high-end 5G chipset used in various performance-tier smartphones.
-
Exynos 9815: Specialized chipset variant for specific regional devices.
-
Exynos 9609: Commonly utilized in mid-range Motorola and Samsung devices.
-
Samsung 3830 (XGO): Frequently seen in the Samsung Galaxy A-series (e.g., A12, A13).
-
Exynos 8895-1703: A specific legacy support configuration for RAM/CPU stacks.
Key Design Features
1. Square-Hole Technology
Unlike cheaper etched stencils that use circular holes, the Amaoe EU5 utilizes laser-cut square holes with slightly rounded corners. This design allows the solder paste to release more cleanly from the stencil, preventing the “clogging” that often leads to uneven ball height. Amaoe EU5 BGA Reballing Stencil-Original
2. Thermal Relief Venting
The stencil surface often includes micro-grooves or “thermal relief” zones. These allow air to escape when heating the chip with a hot air station, significantly reducing the chance of the stencil warping or “popping” due to trapped gasses under the heat. Amaoe EU5 BGA Reballing Stencil-Original
3. Precision Alignment
With a tolerance of ±0.01 mm, the EU5 ensures that every solder ball sits perfectly on its corresponding pad. This is critical for the Exynos 2100, which features a massive number of micro-BGA pins that are easily bridged if the stencil shifts even slightly. Amaoe EU5 BGA Reballing Stencil-Original
Usage Recommendations
To maintain the original specifications and longevity of your Amaoe EU5:
-
Paste Selection: Use a high-quality 183°C (Sn63/Pb37) or 138°C (Low melt) solder paste depending on the chip sensitivity.
-
Cleaning: Clean only with 99% Isopropyl Alcohol (IPA) and a soft ESD-safe brush. Avoid scraping with metal tweezers, which can burr the laser-cut edges.
-
Storage: Store flat in the original sleeve to prevent accidental bending. Even a slight crease in a 0.12 mm stencil can render it useless for CPU reballing.
